What is bookkeeping, in plain words?

Writing down every dollar that comes into the business and every dollar that goes out, with proof, sorted into the categories the tax return uses. For a sole proprietor that is the whole job.

Do I need to learn double-entry accounting?

No. A one-person business filing Schedule C needs income, expenses by category, receipts and a mileage log. Software handles the double-entry underneath; you never see it.

How much time does bookkeeping take for a sole proprietor?

About five minutes a week if you capture receipts on the day you get them. It becomes hours only when it piles up.

Bookkeeping for Absolute Beginners (Sole Proprietors)

Bookkeeping for a one-person business is five rules. Everything else you have read is either for companies with an accounting department or for people selling you a course.

Rule 1: one business account, nothing personal in it

Every business expense from the business account, every personal expense from the personal one. This is the single decision that halves your bookkeeping, because now the bank statement is the list of business transactions. The SBA puts it on the start-up checklist for a reason.

Rule 2: record it on the day, not at month end

A receipt logged today takes ten seconds. The same receipt in a pile on the 30th takes ten minutes, because now you are reconstructing what it was. "Excel at 11pm on the last day of the month" is what rule 2 prevents.

Rule 3: sort by the tax line, not by feeling

The IRS gives you the categories: advertising, supplies, contract labor, software, meals, travel, home office. Use those, because in April they are the only ones that matter. The full list with examples.

Rule 4: keep the proof attached

Amount, date, vendor, what it was for, and the receipt. The IRS can disallow a number with no receipt behind it. Keep records at least three years from the filing date.

Rule 5: know your profit, because tax is on profit

Income minus expenses is the number everything else hangs on: how much to set aside (25% to 30% of it), the quarterly payments, and the return. If you do not know your profit this month, you are not behind on bookkeeping, you are not doing it yet.

What you can ignore in year one

Double-entry, debits and credits. Software does it underneath. You will never post a journal entry.
Accrual accounting. Sole proprietors use cash basis: income when received, expense when paid.
A chart of accounts you designed yourself. Schedule C is your chart of accounts.
Monthly closes and reports beyond "what is my profit". You will want them later; you do not need them now.
